Abstract

The multi-spectral 3D display technology applies left and right lenses coated with multi-layer dielectric film to separate light waves with different wavelengths and then realize three-dimensional watching effect for audience. This paper has developed two spectral division films of 3D glasses, which are coated on left and right lenses of 3D glasses to reach “T≥85%” under waveband range of 421~438nm, 486~521nm and 575~619nm for left lens and under waveband range of 455~463nm, 540~550nm and 640~700nm for right lens and “T<1%” under waveband range of 400~415nm, 450~475nm, 535~560nm and 655~700nm for left lens and under waveband range of 405~450nm, 480~529nm and 570~617nm for right lens. The substrate cleaning technology before coating is applied to improve fastness of the film. The electron beam evaporation and ion assisted deposition system are applied to prepare films. According to test results, the filter complies with application requirements and passes through environmental test. Therefore, this 3D glasses are applicable to watch 3D movies, 3D TV, 3D games and 3D images, etc.
